In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Drill with confidence using the Irwin 23/32 in. x 6 in. High Speed Steel Drill Bit with a Straight Shank. Designed for durability and precise performance, this single-bit tool is ideal for clean, accurate through-holes in metalwork and fabrication projects.

  • Overall length: 6 in.
  • Flute length: 3 in.
  • Shank diameter: 1/2 in.

What makes this Irwin drill bit stand out is the combination of a large-diameter hole with a robust, straight shank that fits securely in standard 1/2" chucks. The HSS construction handles everyday metal drilling tasks—from steel and aluminum to plastics—while the black oxide finish reduces friction and resists corrosion, helping you get more life out of the bit in busy shop environments.

Ideal use cases include drilling clearance and bolt holes for brackets, grommets, and structural hardware where a precise 23/32" hole is required. The 6" overall length provides reach for mid-depth drilling without compromising control, making it suitable for workstations, mechanical shops, automotive repair, and DIY projects.

Practical tips for optimum results:

  • Lubricate with cutting oil or light machine oil when drilling metal to minimize heat and extend bit life.
  • Maintain steady feed pressure and let the bit do the work—avoid forcing the drill to prevent wandering or breakage.
  • Use a drill press or a guide to ensure perpendicular holes for best accuracy, especially on thicker materials.

Keep this 23/32" drill bit ready in its protective tube for easy storage and transport—a reliable, straightforward solution for professionals and serious DIYers tackling larger-hole metalwork with confidence.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
